  • Aqua-Catalysed Chalked Lime Scrubbing Processes and Systems
    Publication number: 20170087510
    Abstract: A dry scrubbing system and process wherein an acid gas comprising at least one pollutant is modified in a humid zone of a duct such that a relative humidity of between 2% and 90% is achieved. The humidified gas is then contacted with chalked lime in a reaction zone. The reaction zone components are subsequently filtered in a filtering zone to provide a filtered gas having reduced concentration of the at least one pollutant when compared to the initial acid gas.

  • Coke separation process in paste plant
    Patent number: 7987992
    Abstract: The invention describes a process and apparatus producing a dense coke fraction from a first particulate coke fraction having a first average density and a first average particle size distribution, stratifying the coke fraction in a density separator into at least two fractions, the at least two fractions comprising a light coke fraction and the dense coke fraction. The dense fraction having an average density greater than the first average density and a particle size distribution substantially equivalent to the first average particle size distribution. The apparatus includes an inclined oscillating table comprising a gas-pervious deck, and a gas mover.
